●Permalloys （PB、PC、PD、PE、PR）

【Usage example 1】

Permalloys for current sensors (PB, PC, etc.)

Permalloys are characterized by high magnetic permeability, low coercive force and low magnetic loss (compared to silicon steel plate). These attributes make them ideal materials for the cores of electronic power steering torque sensors, electrical current and other sensors, magnetic shields, and other applications.

【Usage example 2】

Permalloys for magnetic heads (PC-272)

Permalloys are characterized by high magnetic permeability, low coercive force and low magnetic loss. These characteristics are less affected by molding of the permalloys with resins, making permalloys ideal for the cores of magnetic heads for card readers.

【Usage example 3】

Permalloys for ZCTs (PC-22, PC-2, etc.)

This alloy (PC-22) has high magnetic permeability and low coercive force, and it demonstrates good temperature characteristics. It is most suitable for ZCT cores of electric leakage circuit breakers and as permalloy cores of current sensors for smartmeters.

【Usage example 4】

［Yoke in clock stepping motor］
Permalloys for clocks (PB, PC, PD)

The characteristics of these permalloys are high magnetic permeability, low coercive force and low magnetic losses (compared to silicon steel), making them ideal materials for such products as magnetic shields, and the stators and yokes of stepping motors used as core components of quartz watches.
